Bluelight

Bluelight has introduced a powerful and simple to use network discovery feature for its 1GE and 10GE testers to help raise the productivity of the network testers.
This feature keeps track of physical and logical resources of networks in a non-intrusive way.
The feature supports SNMP and allows the testers to display device statuses, MAC addresses, IP addresses, network usages, OS versions, port information of all the neighboring network-attached devices.
